Nucleic acids also typically contain phosphorous, and nitrogen plays an important structural role in nucleic acids and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.
Answer:
Transcriptional regulators function to regulate the expression of different genes and also to affect the expression of other transcriptional regulators, thereby the combination of a few transcriptional regulators is sufficient to modulate gene expression patterns
Explanation:
Transcriptional regulators are able to control gene expression by binding to cis-regulatory elements on the genome. For example, in plants, MADS-box proteins are transcriptional regulators that contain an evolutionary conserved DNA-binding domain (i.e., MADS-box domain) which regulate simultaneously the expression of many different genes by binding to a conserved DNA motif called CArG box [CC(A/T)6GG] located in the promoter region of many genes expressed at specific stages of plant development. Within the cell, transcription regulators function not only by controlling the expression of different genes but also by affecting each other's activity, thereby creating different combinations where the expression of a limited number of transcription regulators is sufficient enough to regulate gene expression patterns.
The answer is MARITIME TROPICAL.
Hope it helps :))
The main difference between organ and organelle is that organ is a large part of an organism, composed of tissues which perform similar functions whereas organelle is a specialized structure found inside cells, which carries out a specific life process. ... Organelles occur in all eukaryotes. They are microscopic
